Browning the Earth

I read a really awesome article the other day and I wanted to share it.
Some cities and bussinesses are going brown. Their using animal feces for energy.
The city of San Francisco is working towards using dog feces to produce an alternative power source.
There is an estimated 10 million tons of pet waste annually with 6,500 tons alone in San Francisco
Currently feces is being scooped into non-biodegradable bags and dumbed in landfills where it sits for years and years. Feces that aren't scooped up stay on the ground possibly contaminating our water supply over time.
A waste pick up service called Norcal waste will soon be picking up park dog waste in biodegradable bags. This waste will then be processed in a methane digester where fece-eating bacteria produce methane. Then the methane can be used by anything that runs on natural gas or it can be used to generate electricity.
This technology has been used and proven on European farms for over 20 years.
Dog poop is actually ideal waste in this energy producing process because of the protein we feed our dogs.
The droppings should produce as much energy as food scraps which is used for alternative energy.
80 tons of dog feces and food scraps could produce enough energy to power thousands of homes.
I just think this is a wonderful alternative and if we have to pick-up after our dogs and we know its going for this maybe it won't be so hard to pick-up after all.
